Node.js SMS Event Notifications for Edtech Signup Links — Template Ownership and SLOs

Node.js event-notification workers for edtech signup links should emit durable events and render owned template revisions using common API adapters. This design ensures learners receive verification links without delaying web requests or relinquishing copy ownership to providers. Similarly, email event notification APIs must treat events as evidence streams. Services should create immutable report versions and submit messages with stable idempotency keys, separating report versions, message intent, email submission, and event evidence into a practical pipeline.
